Hi Kevin,Kurts PP45 uses a parallel feed ECC99 driver that is CCS loaded, it doesnt use the primary of the IT to load the tube. When he measured LF-3dB it was around 20Hz and that was with 0.33uF parafeed cap!, I remember one of his posts saying it was good to 10Hz with 2uF.
Thanks for your reply to my question regarding loading the secondary of the LL1660 from the other forum, the info was regarding this amplifier here.
45drive45, what value of resistance would you use to load the secondary?.
thanks,
shane
